Your perspective is really helpful! It's a van we could take on but at this stage we'd need to weigh up the time commitment, extent and costs of that work against the costs of instead buying a more pristine van. As it ever is..! Sentiment should have no part in this decision, but I'd love to give it a home

Unless its up for a few hundred quid and you can or know someone who can weld, I'd think twice personally. My experience has taught me a valuable lesson. I fell for my van upon seeing it and in reality I should have walked away.
You can get good solid vans still in the 2.5-3k region (sometimes less), don't do what I did and buy the first you took a shine to. My van looked relatively good but was a series of bodge repairs and carefully hidden issues that I've had to slowly undo. An original £900 of welding, almost doubled with hidden horrors found during the process.
At least your van is an honest one in that you can see the problems but imagine if that is what you can see, what can't you see?
I can honestly say I have spent in the region of 4-4.5k on my restore, when you add in the paint job inside and out, new parts, panels, seals, etc. etc. restoring my van which is way more than I paid for it and it looked better than that to start with.
I could probably have just bought a good solid original van for similar money than I've paid (and if I had waited until winter it seems even less). Depends what you want, I have enjoyed the process and project managing, and the van now feels like mine and no-one elses. however it has eaten all my cash albeit slowly over time and not in one big lump.
I love my van and I'm glad I restored it, its 100% mine now, solid, but were a lot of hidden costs in restoring above and beyond the welding and I honestly think the advise above is right. It will cost you far more in the long run to "do up a duffer" than to buy and maintain a good example.
Let the head rule the heart in this situation is my advice.
